Description

Suitable for A-class power amplifiers, B-class power amplifiers, AB class power amplifiers, digital power amplifiers. In short, any power amplifier board that requires positive and negative dual voltage power supply can use this power supply (such as traditional discrete component power amplifiers, LM1875, LM3886 and other integrated circuit power amplifiers). It should be noted that the voltage of the power supply should be selected below the maximum allowable voltage of the power amplifier board

The power output is a direct current voltage, which can eliminate the need for conventional ring voltage rectification and filtering circuits. Not only is it more efficient and generates less heat, but the internal resistance of the power supply is also much lower. Output terminals:+ 36V, G, and -36V are respectively connected to the+, 0, and - power supply terminals of the power amplifier board+ 12V and G can be connected to a small fan for auxiliary heat dissipation or speaker protection circuit, etc... (Two G's are interconnected inside the power supply, and can be connected to either one or the other, or connected together.)

Input terminals: L and N are respectively connected to the live and neutral wires of a 220V plug. FG can be connected to the casing or ground wire using pure aluminum heat sink and casing. There are three M3 fixing holes in the middle of the bottom, which can be fixed on the chassis or on a larger heat sink

There are also 2 M3 fixing holes on each side, and a heat sink or side mounting can also be installed. This power supply is designed specifically for amplifier circuits, with a pure aluminum shell for heat dissipation and shielding, and very low ripple interference
Dimensions (length * width * height): 127mm * 82mm * 38mm
